No evidence of Koala was found during surveys for this proposal, nor in previous surveys (MV2L Alliance, 2011). During field investigations and the habitat assessment, ‘habitat critical to the survival of the Koala’ (DSEWPaC, 2012) was considered, but no evidence was found to support Koala activity in the study area.
Although there were three scattered records in the locality during the last 20 years (see figure below) and there are known populations in Wollemi National Park, there are no known populations in the study area. The study area provides marginal foraging opportunities with uncommon secondary food trees such as the Brittle Gum (Eucalyptus mannifera) and supplementary food tree Blaxland’s Stringybark (Eucalyptus blaxlandii). The proportion of food trees is considered to only provide tertiary habitat (DECC, 2008).
